Title: Wireless signal transmission system for rear projector
Inventor: OGAWA MASUMI
IPC: H04N5/74
Filed: 1991-01-24
Abstract: PURPOSE:To obtain a wide transmission range by arranging a signal transmission lighting means to a rear side of a screen and allowing a light radiating from the lighting means to radiate externally through the screen. CONSTITUTION:The system is provided with a screen 2 of a rear projector 1, a projection tube 4, a radiation lens 6, and a mirror 8. Then a lighting section 100 radiating a voice transmission infrared ray is placed on the rear side of the screen 2 and the light emitting element 16 is arranged to be directed toward the screen 2. The arranged position of the lighting section 100 is preferably located to a location not hindering the optical path of the light radiating from the projection 4, e.g. under the screen 2. In this case, an infrared ray modulated by a voice signal radiates from the light emitting element 16 of the lighting section 100 and since the infrared ray radiates externally through the screen 2, a wide transmission range is attained depending on the light diffusion function of the screen.

IPC: H04J13/00
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To shorten the time of code synchronous detection of spectrum spread and to prevent the degradation of synchronous detection characteristics in a CDMA mobile communication system. SOLUTION: On the transmission side, first, second,..., N-th spread codes are used for (a+1)th, (a+2)th,... (a+N)th symbols ((a) is an arbitrary integer) of information modulation symbols on the transmission side to perform spectrum spread and transmission. On the reception side, matched filters 22 to 24 matched to first,..., N-th spread codes are used to obtain a correlation waveform from a reception signal. A delay circuit 25 is used to delay this correlation waveform by 0 to N-1 information modulation symbols times, and the sequence of peak detection of correlation is detected to perform discrimination of a base station and detection of code synchronization. Thus, the time of code synchronous detection is shortened and the degradation of synchronous characteristics is prevented in comparison with the use of a sliding correlator.

Abstract: PURPOSE:To measure the beam diameter and the expansion angle of a transmission laser beam accurately by determining the beam diameter of a laser beam to be measured from the value of an angle of inclination remotely detecting the expansion of a reflected light from a long and narrow reflecting target arranged at the angle of inclination on the axis of the laser beam to be measured. CONSTITUTION:A long and narrow target 14 is set at a distance rho from a laser radar 10  inclined at an angle theta with respect to a laser beam 13 to be measured. A reflected light 15 from the target 14 is received with a receiving optical system 16 of the laser radar 10 and detected with a detector 17. An oscilloscope 18 traces the reflected light 15 with the output of the detector 17. When the width (diameter) of the target 14 is represented by (a) and the waveform of the reflected light 15 observed on the oscilloscope  18 is large in the expansion, the diameter (d) of the laser beam 13 at the distance rho is given by d=(C/2)(t-tau)tantheta. Therefore, if the pulse width tau of a transmission laser beam  13 and the set angle theta of the target 14 are defined, the diameter (d) of the transmission laser beam 13 can be determined at the distance rho by measuring the expansion range (t) of the reflected wave 15 with the oscilloscope 18 (where (c) is the velocity of light).

Abstract: PURPOSE:To improve erosion resistance and wear characteristics in a composite material comprising Al2O3 as a matrix and SiC particles a dispersible material, by specifying particle size of SiC particles and the amount of the particles added and making a specific high density. CONSTITUTION:This wear-resistant composite material consists of 20-50vol.% SiC particles having 0.5-2.0mu average particle diameter and the rest of Al2O3 and has >=98% relative density. The composite material is obtained by blending Al2O3 powder with SiC powder and sintering the mixture. In the case, when the average particle diameter of SiC is <0.5mu, a composite material containing 50vol.% SiC can not be processed to have the above-mentioned density even by hot press, etc. and when >2.0mu, the composite material is slightly sintered in a dense state. When the content of SiC is <20vol.%, improvement in erosion resistance and wear characteristics is insufficient and when >50vol.%, a dense sintered material is not obtained. When relative density is <98%, hardness is insufficient and erosion resistance is not obtained even if SiC content is 40-50vol.%.
